Just to provide a different perspective than what we hear in our news media...
The gender bias of people speaking about rape is so obvious in our culture.
You always hear "as soon as we're sure the guy did/didn't do it..." ; never "as soon as we're sure the person did/didn't do it...."
Studies show that male-on-male and female-on-male rape is INCREDIBLY unreported and unhandled, and that our legal and forensic systems are hardly prepared to accept cases of them because of our sociocultural bias towards rape. When a man is raped he doesn't just have to deal with the (already crippling) act of being raped, but he also has to struggle with his mental image as a man, and with the backlash from society that one of the following must apply to him; he was overpowered and thus his gender role of being "strong" is challenged and he is most likely emasculated, he could not possibly be raped because men are not capable of denying consent, et cetera.
Not the most critical perspective to take on rape, but it is an important bias of ours to consider when talking about rape. So often rape is kept in such a narrow discussion in our mainstream media.
